Explanation / Answer

for a particular reaction

dG = dH - TdS
dG = +14200 Joules - (298K)(-198.5 J/K)
dG = +14200 Joules - (59153 Joules)
dG = - 44953 Joules
your answer is
dG = - 44.953 kJ

b)

the system is spontaneous as written

because the reaction is spontaneous at 298 K under standard conditions
